    Global Accelerator:CreateCustomRoutingEndpointGroups

    Last Updated:Apr 10, 2024

    Creates endpoint groups for a custom routing listener.

    Operation description

    Global Accelerator (GA) forwards client requests to endpoints in an endpoint group based on the routing type of the listener that is associated with the endpoint group.

    • After you configure an intelligent routing listener for a GA instance, the GA instance selects a nearby and healthy endpoint group and forwards client requests to a healthy endpoint in the endpoint group.
    • After you configure a custom routing listener for a GA instance, the instance generates a port mapping table based on the listener port range, protocols and port ranges of the associated endpoint groups, and IP addresses of endpoints (vSwitches), and forwards client requests to specified IP addresses and ports in the vSwitches.

    You can call this operation to create endpoint groups for custom routing listeners. For information about how to create endpoint groups for intelligent routing listeners, see CreateEndpointGroup .

    When you call this operation, take note of the following items:

    • CreateCustomRoutingEndpointGroups is an asynchronous operation. After you send a request, the system returns a request ID and runs the task in the background. You can call the DescribeCustomRoutingEndpointGroup or ListCustomRoutingEndpointGroups operation to query the status of the endpoint groups that are associated with custom routing listeners.

      • If one or more endpoint groups are in the init state, it indicates that the endpoint groups are being created. In this case, you can perform only query operations.
      • If all endpoint groups are in the active state, it indicates that the endpoint groups are created.

    • The CreateCustomRoutingEndpointGroups operation cannot be called repeatedly for the same GA instance within a specific period of time.

    Prerequisites

    Make sure that the following requirements are met before you call this operation:

    • A standard GA instance is created. For more information, see CreateAccelerator .
    • A bandwidth plan is associated with the standard GA instance. For more information, see BandwidthPackageAddAccelerator .
    • An application is deployed to receive requests that are forwarded from GA. You can specify only vSwitches as endpoints for custom routing listeners.
    • The permissions to use custom routing listeners are acquired and a custom routing listener is created for the GA instance. Custom routing listeners are in invitational preview. To use custom routing listeners, contact your account manager. For more information about how to create a custom routing listener, see CreateListener .

    Debugging

    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

    Request parameters

    ParameterTypeRequiredDescriptionExample
    RegionIdstringYes

    The ID of the region where the GA instance is deployed. Set the value to cn-hangzhou.

    		cn-hangzhou
    ClientTokenstringNo

    The client token that is used to ensure the idempotence of the request.

    You can use the client to generate the token, but you must make sure that the token is unique among all requests. The token can contain only ASCII characters.

    Note If you do not set this parameter, ClientToken is set to the value of RequestId. The value of RequestId for each API request is different.
    		123e4567-e89b-12d3-a456-426655440000
    DryRunbooleanNo

    Specifies whether to perform a dry run. Valid values:

    • true: performs a dry run. The system checks the required parameters, request syntax, and limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the DryRunOperation error code is returned.
    • false (default): performs a dry run and sends the request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.
    		false
    AcceleratorIdstringYes

    The ID of the GA instance.

    		ga-bp1odcab8tmno0hdq****
    ListenerIdstringYes

    The ID of the custom routing listener.
